Description
Jan. 6, 1942. vo T I 2,268,973
Filed Jan. 27, 1941 Patented Jan. 6, 1942 I Henry G.Voight, New Haven, Conn., assignor to Sargent & Company, New Haven, Conn., a corporation of Connecticut Application January 27, 1941, Serial No. 376,019
3 Claims. (01. 292-169) This invention relates to door locks or latches, and more particularly to alock for the front door of a building, although it will be understood that it may be employed in any location in which is desired a lock having theinovel characteristics embodied in the present structure.
Moreover, the invention relates also to a socalled tubular lock, or a lock having a cylindrical casing which may be inserted through a cylindrical opening made in the edge of a door, and is in many respects similar to the lock shown in my application Serial No. 345,109, filed July 12, 1940, the present structure embodying improvements over or additions to the device shown in that application. i
In the application above referred to, the lock is provided with a dogging plunger accessible from the face of the door when the latter is closed to dog the latch against operation by the outer knob. This plunger is guided in the walls doorfor operation when the door'is closed, with a Walking beam structure whereby the dogging means may be moved either to inoperative or operative position by pressure upon a button at the face of the door. I
A still further'obje'ct oi the invention is the provision of a lockof the character described having a knob-dogging plunger and a walking beam structure arranged within the knob rose at the inner side of the door to operate said plunger,
thewalking beam structure comprising 'a pair 01 of the case and is pushed inwardly to dog the outer knob against operation. Detent means are provided to releasably hold the dogging member inoperative position until it is manually released, which release is effected by pulling the plunger outwardly by the exposed portion thereof. While such a device operates in a satisfactory manner for the most part, it is found that it is easier to .push the plunger inwardly than it is to grasp the exposed end thereof and pull it outwardly.
The present invention is designed to overcome this disadvantage, and to provide a pair of push buttons connected by a walking beam, and also operatively connected to the dogging member so that one of these buttons is pressed inwardly to dog the latch against operationwhile the other is pressed inwardly to release the dogging means, the movement of one button to its inner position serving through the walking beam to draw the other button to its outer position, and vice versa. I
One object of the present invention is the pro vision of a door lock having improved means for operation of the latch-dogging means, particularly with respect to moving such means to inoperative position.
A still further objector the invention is the ter is closed, with improved means for withdrawing the dogging member to inoperative position. A still further object of the invention is the provision of a lock having a knob-dogging member extending outwardly through the face of the push buttons or like members extending through the rose to be accessible for operation at the inner side of the door whenthe latter is closed.
To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.
In the accompanying drawing:
Fig. 1 is a front. elevational view of a door having my improved lock applied thereto, the knob having been removed for the sake of clearness;
Fig. 2-is a sectional view on line 2-2 of Fig. 1;
Fig. 3 is an interior face view of the inner rose and walking beam structure housed therein;
Fig. 4 is a sectional view on line 4-4 of Fig. 3;
Fig. 5 is a sectional View of the walking beam structure taken on line 5-5 of Fig. 3; and
Fig. 6 is a detail elevational view of the walking beam.
To illustrate a preferred embodiment of my invention, Ihave shown a portion of a door at 10, upon which is mounted a lock comprising a tubular casing I I having reciprocably mounted therein a bolt [2 normally urged outwardly by the bolt spring l3, which acts against the bolt head and against a post It provided on the walls of the easing. The lock may also be provided with a boltcontrolling plunger I5 of usual form, which serves, as shownin my prior application above referred to and as is well known in the art, to prevent the retraction of the bolt by a tool inserted between the edge of the door and the door jamb.
Rotatably mounted in the walls of the casing are inner'and outer hubs I6 and I1 carrying rollbacks l8 and [9, respectively. These rollbacks are operated by inner andouter knob spindles 20 and 2|, respectively, upon which are mounted the inner and outer knobs 22 and 23. It will be understood that the spindles 20 and 2| are independently operable by their respective knobs, so that either of the knobs may be rotated independently 'of the other to rotate the rollback carried. thereby and retract the latch l3. As the abovedescribed structure and the connections between the rollbacks l8 and I9 and the bolt |2 may be identical with the corresponding parts shown in my previous application referred to, it is deemed unnecessary to further illustrate them herein.
Slidably mounted in the opposite walls of the lock case M is a plunger 25 carrying a detent 26 adapted to engage in a recess 21 in a laterally extended portion of the rollback l9 operated by the outside knob, so that, when the plunger is pushed inwardly from its position shown in Fig. 2, and the detent engages in the recess 21, the rollback l9 will be dogged against operation. The plunger is releasably retained in its inner and outer positions by means of the engagement of the spring-pressed detent 29 with a projection 30 arranged on the side of the plunger 25 opposite that which carries the detent 26.
A push button 3| is adjustably connected by means of its threaded end 32 with the plunger 25, the button extending outwardly through an opening in the inner rose 33 so as to be accessible for operation at the inside of the door at one side of the shank of the knob '22. This push button is provided with an intermediate reduced portion 34 for a purpose which will be hereinafter described. This push button 3| may be provided with a recess 35 within which extends a finger 36 on the rose 33 to prevent rotation of the button after the rose has been secured upon the door by means of the screws 31 (Fig. 1).
It will be apparent that with the foregoing structure the push button 3| may be pushed inwardly so as to move the plunger 25 inwardly to knob-dogging position. In order that the plunger may also be moved outwardly by pressure upon a button at the inside of the door, a walking beam structure is provided and disposed within the rose 33, as will now be described.
This structure comprises a casing or housing formed of spaced plates 40 and 4|, the plate 40 having upper and lower portions 42 and 43 turned laterally and embraced by crimped portions 44 and 45 so as to conveniently and cheaply secure the two plates in spaced relation. These plates are provided with aligned openings 46 and 41 through which passes the knob spindle, and each of these openings has upper and lower extended recesses 48 and 49 into which swivelly projects semi-circular members and 5| secured upon each side of a walking beam 52 at both upper and lower edges thereof, so that the walking beam will be swiveled or pivoted between the two plates for rocking movement about a vertical axis.
The button 3| extends through openings in the plates 40 and 4|, and the reduced portion 34 thereof is received in a recess 53 in one end of the walking beam, so that when the latter is moved pivotally the button will be moved longitudinally, and vice versa. The walking beam 52 is provided with a central opening 54 through which the inner knob spindle 23 loosely passes, and upon the end of this member opposite the recess 53 is mounted a second push button 55 which extends outwardly through openings in the plate 4| and rose 33 so as to be accessible for operation at the inside of the door.
The assembled position of the parts of the .walking beam structure is shown in Fig. 5, and
plunger 25 until the rear plate 40 engages the face of'the door. The rose is then applied and secured in position by the screws 31, and if necessary the button 3| may be backed ofi a short distance so as to cause the groove 35 to register with the tongue 36 in the rose. The walking beam structure will by this means be mounted in position, and the buttons will be substantially concealed by the inner knob, but will be readily accessible for operation. When the button 3| is depressed, the detent 26 will engage the rollback l9 so as to prevent operation of the outside knob. Vhen it is desired to release the dogging member, the button 55 will be depressed, which will throw the opposite end of the member 52 outwardly, and thus draw outwardly the button 3| and the plunger 25 so as to withdraw the detent 26 from the recess 21, thus leaving the bolt free for retraction by the outside knob.
The outer plate 4| may be provided with upwardly and downwardly extending ears 56 on each side of the members 45, which ears are adapted to embrace the inwardly displaced sleeves 51 around the openings in the rose which receive the screws 31, so that the walking beam structure will be held against displacement within the rose.
While I have shown and described a preferred embodiment of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the appended claims.
What I claim is:
1. In a door lock, a case, a bolt reciprocably mounted therein, independently rotatable inner and outer knobs, mechanism connecting each of said knobs to said bolt for operation thereof, a dogging member slidably carried by the walls of the case to dog the outer knob against operation, a walking beam structure for operating the dogging means accessible for operation at the inside of the door when the latter is closed. a rose about the inner knob, said walking beam structure being housed within said rose, 'said structure comprising a pair of plates, a lever pivoted between said plates at a point intermediate its ends, a push button operatively connected to each end of the lever and projecting through said rose, and one of said buttons being directly connected to said dogging member.
